#include 
#include 
intptr_t  _dyld_get_image_vmaddr_slide(uint32_t image_index);

// 获取第一个模块（主模块）的基址
intptr_t  base_addr = _dyld_get_image_vmaddr_slide(0);

// 遍历所有模块的基址
_dyld_image_count()获取模块数量

for(init i = 0; i < _dyld_image_count(); i++)
{
     intptr_t  base_addr = _dyld_get_image_vmaddr_slide(i);
}
